Where pipe is concealed, clipping may only be required where necessary. |
• Expansion (PEX pipe). 1% on length between 20°C and 82°C. | |
• Flow rates. Comparable with metal systems. | |
• | Clean rs, in ibitors and descalents. For advice on the replenishment of |
| additives such as corrosion inhibitors, the following manufacturers should |
| be contacted: Fernox Manufacturing Limited on 01799 550811 or Sentinel, |
| BetzDearborn Limited on 0151 420 9595. |
• Paint and Chemicals. Use only water or oil based paint. Collet covers | |
| prevent paint ingress into fittings. DO NOT ALLOW CONTACT WITH |
| oil based jointing compounds, cellulose based paints, paint thinners, paint |
| strippers, solder flux, acid based descalents or aggressive cleaning products. |
• | Solder Flux. No fluxes of any types should come into contact with |
| JG Speedfit Pipe and Fittings. If fluxes are to be used in an environment |
| where Speedfit is installed, then (1) extreme care should be taken to ensure |
| that no such contact takes place and (2) JG recommend installers only use |
| fluxes tested and approved in writing in advance by JG. At the date of this |
| publication, the only such approved flux is Fernox Flux. |
• Chlorine. Speedfit is not suitable for use in systems where the water | |||
| contains high levels of chlorine. e.g. swimming pools, fountains etc. | ||
• | Exposure to | . Speedfit products, when used indoors, are not | |
| affected by sunlight. When used outdoors protect from ultra violet light | ||
| by lagging or painting. | ||
• Pipe clips. Pipe clips should not be fitted any closer than 60mm from the | |||
| end of the fitting. Pipe should be adequately supported by pipe clips to | ||
| prevent undue stress (side load) on fittings. | ||
• Pipe inserts. Must be used on all installations when using plastic pipe | |||
| and should be fully inserted. Only use a Speedfit Insert with Speedfit Pipe. | ||
• Metal Joists. When ʻcablingʼ plastic pipe through metal joists ensure rubber | |||
| grommets are in place to prevent damage to pipe. Use of collet covers or | ||
| collet clips on fittings recommended. | ||
• | Conn | ction to boil rs. A minimum 1000mm run of copper pipe must be | |
| installed between the boiler and the Speedfit system, as per BS5955: Part 8. | ||
• | Connection to | pper pi . 450mm is the minimum distance to make | |
| a solder connection on copper pipe inserted into a Speedfit Fitting. Ensure | ||
| that any residual flux solder does not come into contact with the fitting. | ||
• Concrete and masonry. Speedfit pipe and fittings can be laid in concrete | |||
| and masonry providing they are installed in conduit pipe with access boxes | ||
| for the fittings. This is to enable the pipe to expand and provide accessibility | ||
| for both pipe and fittings. As stated in Water Regulation Scheme 2.7 and BS | ||
| 8000 : Part 15, fittings and pipe should be removable for possible replacement. | ||
| Insulation is also recommended to protect against heat loss and the effects | ||
| of frost. |
| |
• Electrical continuity. If Speedfit is used in an existing metal system which | |||
| may have been used for earthing, electrical continuity should be reinstated. | ||
• Valves and taps. Plastic 15mm and 22mm valves and taps available from | |||
| JG Speedfit Ltd are not suitable for central heating installations. | ||
• Collet Covers. | Collet covers provide added security against pipe | ||
| disconnection, e.g. the fittings coming into contact with rigid surfaces | ||
| and behind | ||
| in red or blue to provide colour coding of pipe. | ||
• Collet Clips. Grey collet clips are used with standard fittings to prevent | |||
| accidental pipe disconnection. Red or blue clips provide colour coding | ||
| of pipe. Red and blue clips should not be used to prevent accidental | ||
| release of pipe. |
| |
• System testing. To ensure the pipework and fittings have been installed | |||
| correctly, whether it be on a new or extended system, it is essential that the | ||
| system is checked and hydraulically wet tested. Testing should be at 2 bar | ||
| for 10 minutes and 10 bar for 10 minutes. This testing, combined with other | ||
| relevant checks, should reveal installation problems and is regarded as good | ||
| plumbing practice. However, system testing should not be regarded as a | ||
| substitute for correct installation (see also “Making a Good Connection”). | ||
• | Syst | flushing. As is usual practice for any plumbing installation, flushing | |
| of thesystem prior to the use of Speedfit is recommended to remove any | ||
| contaminants/chemical residue from elsewhere in the system. |
British Gas Service has accepted the John Guest Speedfit fittings as being
• suitable for open vented and sealed central heating systems and as eligible for acceptance onto its service contracts.
Speedfit products will need special protection in vermin infested areas.

Plastic threads are not generally as
• strongMaximumas brassTorquethreadsfigures. Customers(BSP & BSPT)and end. users should be aware of this when choosing products for their applications. Overtightening of plastic threads will cause undue stress and eventual cracking and leakage. The maximum torque figures for BSP and BSPT threads used on Speedfit plumbing products in mating threads conforming to the relevant BS or International thread standards are shown below.

It is recommended that all installations are checked prior to use to determine that seal has been made.
Fittings should not be subject to excessive side loads and they

| should be fully inserted. | ||
• | Electrical Compo | nts. Electrical products in the Speedfit Underfloor Heating | |
| Systems are designed only to be used in U.K. Electrical Supply situations. | ||
• Electrical Continuity. If Speedfit is used in an existing metal system which | |||
| may have been used for earthing, electrical continuity should be reinstated. | ||
• | Coll | Clips. White and Grey collet clips are used with standard fittings to | |
| prevent accidental pipe disconnection. Red or blue clips provide colour | ||
| coding of pipe. Red and blue clips should not be used to prevent accidental | ||
| release of pipe. |

| - Screwed pipe. |
|
|
|
| - LDPE (to BS1972 Class C and Class D) in 1/2” and 3/4” inch sizes. | |||
• Pipes. Speedfit Underground Fittings can be used with:- | ||||
| - Blue MDPE pipe to BS6572. |
|
|
|
| - Black MDPE pipe to BS6730. |
|
|
|
| - Pipes conforming to ISO161/1, ISO3607 and DIN16893. | |||
• Working Temperatures and Pressures. | Maximum working pressure | |||
| 12 Bar @ 20˚C. |
|
|
|
• St ndards. Speedfit Underground Fittings are approved by the | ||||
| Water Regulations Advisory Scheme. |
|
| |
• Performance. The fittings are manufactured from tough plastic | ||||
| material well able to meet the stringent requirements of the water | |||
| industry. They have been approved by the WRAS and, as such, | |||
| have passed the ʻpull out testʼ where a force shown below is applied | |||
| to a connection between MDPE pipes and a fitting for 5 minutes | |||
| without the connection failing. | 20mm | Size | 25mm |

• DO NOT USE FOR Gas, fuel oil or compressed air applications
| or hot water. |
|
• Chemical Effects. For below ground applications the fittings require | ||
| no additional preparations - coating etc. When used above ground, | |
| avoid contact with aggressive chemical compounds. Protect from frost | |
| where necessary. In the United Kingdom, potable water does not | |
| contain high levels of chemicals (eg chlorine etc) that would adversely | |
| affect Speedfit Underground Fittings. | |
• Exposure to sunlight. Permanent exposure to direct sunlight will | ||
| necessitate lagging the fittings. | |
• Pipe Inserts. | Pipe inserts must be used and fully inserted on all | |
| connections to MDPE or LDPE pipe. | |
• System T sting. Pressure test to 1.5 times working pressure for 10 | ||
| minutes before connecting to the mains supply. It is recommended | |
| that all pipe and fitting installations are pressure tested after | |
| installation before handing over to the final user | |
• Maximum Torque Figures. The maximum torque figures for BSP | ||
| and BSPT threads used on Speedfit products are as follows:- | |
1/2 | 3.0 Nm | |
| Size | Maximum Torque |
| 3/4 | 4.0 Nm |
It is recommended that all installations are checked prior to use to determine that a seal has been made.
The maximum torque figures quoted for use with Speedfit fittings are dependent on the mating thread conforming to the relevant British International thread standards.
